PAPER STOCK REFINING ENdNE Filed. Nov. 1,3, 1950 j anfrv ww ww @wif/@ Patented June 14, 1932 UNITED STATES PATENT ori-"lcs GUY S. BRAZEAU AND HENRY P. MADSEN, OF APPLETON, WISCONSIN, ASSIGNORS TO APPLETON MACHINE COMPANY, OF APPLETON, VISCONSIN PAPER-STOCK-REFIN ING ENGINE Application filed November 13, 1930. Serial No. 405,469.

This invention relates to paper-stock reiining engines of the Jordan type, and more particularly to a refining engine, which is directly driven by an electric motor.

Heretofore, in motor driven engines of the foregoing type, it has been customary to mount the motor on the engine base in alignment with the engine sha-ft, and connect the motor and engine shafts by a flexible coupling. This has numerous objections, in that an exceedingly long and heavy machine result-s, which increases the cost materially, and requires an excessive amount of space. Also, in arrangements of this kind, four bearings I are required, two for the engine shaft and two for the motor shaft, and the work of removing the engine plug is tedious and lengthy.

It is the primary obj ect of the present invention to overcome the foregoing objections and provide an exceedingly compact, light, and comparatively inexpensive refining engine of the foregoing type, in which the electric motor is connected directly upon the engine shaft, the same being journalled in only two bearings, thus materially reducing the length and bulk of the engine, eliminating the expense of a flexible coupling and additional bearings, and facilitating removal and insertion of the plug.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination, and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawing, Figure l is a longitudinal section through a conventional type of J ordan engine constructed in accordance with the present invention, and parts broken away and in section to more clearly illustrate structural features; and

Figure 2 is a reduced transverse section taken on the line 2-2 of Figure l.

Referring now more particularly to the accompanying drawing, the numeral l designates a base having mounted adjacent its opposite ends, standards 2 and 3, upon which anti-'frictional bearings 4 and 5, respectively, are slidably mounted. Secured on the base, intermediate its ends, is a conventional tapered shell 6, having disposed therein the usual plug 7, which plug is keyed on the shaft 8, having its outer ends journalled in the bearings l and 5, it being understood that the bearings l and 5 are slidably mounted to compensate for longitudinal adjustment of the shaft 8 and the plug 7 to regulate the refining process.

In general, the foregoing structure is conventional and forms no specific part of the present invention other than in the combination as hereinafter claimed.

Mounted upon the base l intermediate the bearing 4 and the rear end of the shell 6, is an electric motor 9, the housing lO of which is secured on the base in any suitable manner.

The rotor l1 of the motor 9 is keyed or secured in any suitable manner upon the plug sha ft 8 thus serving to directly drive the shaft and plug.

From the foregoing explanation taken in connection with the accompanying drawing, it will be readily appreciated that an exceedingly compact structure has been provided, in which only two bearings are required, the motor bearings being entirely eliminated, and in which the necessity of a flexible coupling is avoided.

Obviously, reducing the length and bulk of the machine also reduces the amount of material required, thus reducing weight, as well as cost, and providing an engine which can be installed in an exceedingly compact space.

It will also be appreciated that removal of the plug 7 is materially facilitated, in that it is merely necessary to remove the anti-frictional bearing 5 and the head of the shell 6 to allow for withdrawal of the shaft and plug,

the rotor then being supported Within the motor eld.

We claim:

1. A paper-stock-refining engine comprising a base, a shell mounted 0n said base, a plug shaft extending through -suidshell7 a bearing supported on said Vheise for each end oi said shaft, and an electric motor mounted on said hase inside of the adjacent hearing, the rotor of said motor heing keyed directly on said shaft.

2. A paper-stock-rening engine compris-pl ing a base7 a shell mounted on said base, a'

support mounted on said base yadj acent each of its ends7 removable hearings slidahly mounted on said supports, a plug shaft heving its ends journalled in-said bearings, and an electric motor mounted on said .bese he tween. one of said hearingsend said shell, seid plug shaft extending through said motor and the rotor of said motor being keyed directly on said shaft.

' In testimony that We claim the foregoing We have hereunto set our hands at Appleton,

in the county of Outagame and State of l/Visconsin.
